Analysis of designs of modern stretch-forming dies for lineforming aircraft skin

Abstract

Тенденции развития науки и образования guidelines for assessing satisfaction and improving the quality of services provided. In our opinion, special attention should be paid to sections of the standard. ISO 9000 is related to customer requirements because passengers are direct consumers of the service. Therefore, in the system of long-distance transportation, mechanisms for assessing customer satisfaction should be developed and applied.

Stress Simulation of the Structure of a Stretch Die Made by Fused Deposition Modeling

“…The main drawback of this material is a high dynamic coefficient of friction in contact with workpieces from aluminum alloys 0.25 ... 0.3 [2]. To reduce the coefficient of friction, it is necessary to use lubricants or apply anti-friction coatings [3]. Stretch-forming dies are made by casting followed by machining of the working surface.…”
